Donald Trump is the most despicable President in American history, not because he negotiates with authoritarian dictators in the hope of avoiding conflict, but because he, publicly and privately, will take their word, and believe what they say, when they deny murderous activities against Americans and against journalists.
So we have Mohammed bin Salman who was well aware and responsible for the horrific murder of American journalist and Saudi Arabian national Jamal Khashoggi in October 2018.
So we have Kim Jong Un who was well aware and responsible for the mistreatment, torture and death of American student Otto Warmbier in 2017.
So we have Vladimir Putin who has arranged the death of journalists and other critics who have been murdered outside the Kremlin and in foreign nations by chemical agents, and also denies involvement in the 2016 Presidential election in the United States in favor of Trump over Hillary Clinton.
By publicly accepting these three liars and their denials, Trump adds to his reputation as a massive liar, who has no concern for human rights and common decency.
In so doing, Donald Trump degrades the moral authority of the American Presidency, and besmirches the office.
For that, he will be condemned in history, and it will cement his last place status among Presidents, below James Buchanan and Andrew Johnson.
